20行莫名其妙的语法错误，教材文件复制粘贴过来都不行

import requests 
import pygal
from pygal.style import LightColorizedStyle as LCS, LightenStyle as LS

url = 'https://api.github.com/search/repositories?q=language:python&sort=stars'
r = requests.get(url)
print("Status code.",r.status_code)

response_dict = r.json()
print("Total repositiories:",response_dict['total_count'])

repo_dicts = response_dict['items']
print("Repositories returned:",len(repo_dicts))

names,stars = [],[]
for repo_dict in repo_dicts:
	names.append(repo_dict['name'])
	stars.append(repo_dict['stargazers_count']
	
my_style = LS('#333366', base_style=LCS)

chart = pygal.Bar(style=my_style,x_label_rotation=45,show_legend=False)
chart.title = 'Most-Starred'
chart.x_labels = names

chart.add('',stars)
chart.render_to_file('python_repos.svg')

stars.append(repo_dict['stargazers_count']

少了个括号

stars.append(repo_dict['stargazers_count'])

楼上正解，18行结尾少了右括号，括号未闭合。如果你使用vscode作为ide的话，可以安装pylance（https://marketplace.visualstudio.com/items?itemName=ms-python.vscode-pylance）获取错误提示

具体语法错误是？

invalid syntax
